[0002] Forklifts are tools used to move goods, and are generally divided into electric forklifts and hand forklifts.

[0003] A hand-operated forklift is a manually operated logistics handling device, mainly used for lifting, carrying, and lowering palletized goods. When in use, it is equipped with a set of support wheels on its support arm. When carrying goods, if there is a deviation in the weight of the goods or a deviation in the placement of the goods when lifting them, the hand-operated forklift is prone to tilting to one side, causing the goods to tip over and the forklift to lose its balance. Utility Model Content

[0004] The purpose of this invention is to provide a device for controlling the balance of the forklift support wheels, in order to solve the problem mentioned in the background art that once there is a deviation in the weight of the goods or a deviation in the placement of the goods when lifting them, the hand-pushed forklift is prone to tilting to one side, causing the goods to tip over and the forklift to lose balance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for controlling the balance of a forklift support wheel, comprising a support arm and a mounting plate. A fixing block is fixedly connected to the outer surface of the support arm. The mounting plate is connected to the outer surface of the support arm via the fixing block. A screw is connected through the surface of the mounting plate. An adjusting block is fixedly connected to the surface of the mounting plate. An adjusting groove is formed on the surface of the adjusting block. A limit groove is formed on the inner side of the adjusting groove. A sliding plate is slidably connected to the inner side of the adjusting groove. A support block is fixedly connected to the surface of the sliding plate. A rotating wheel is movably connected to the side of the support block away from the sliding plate.

[0006] Preferably, the mounting plate has a U-shaped cross-section, the fixing block has an L-shaped cross-section, and the mounting plate and the fixing block are connected by a hook.

[0007] Preferably, the surface of the mounting plate has a through hole, through which the screw passes through the surface of the mounting plate.

[0008] Preferably, the outer surface of the fixing block is provided with a screw groove, the screw and the screw groove are threadedly connected, and the mounting plate is connected to the fixing block through the screw and the screw groove.

[0009] Preferably, a limiting block is fixedly connected to the outer surface of the skateboard, and the limiting block and the limiting groove are slidably connected.

[0010] Preferably, the slide plate is slidably connected to the adjustment block via an adjustment groove, and the support block acts below the adjustment block via the slide plate.

[0011] Preferably, the sliding plates are distributed in two groups on the surface of the support block, the outer surface of the sliding plates and the inner wall of the adjustment groove are slidably connected, and the support block and the mounting plate are distributed on both sides of the support arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By connecting the support arm and the fixed block, and then connecting the mounting plate and the adjusting block, and finally connecting the adjusting block and the adjusting groove, and the adjusting groove and the limiting groove, and finally connecting the sliding plate and the limiting block, the distance between the support block and the adjusting block can be adjusted. Under the sliding contact of the sliding plate and the adjusting groove, the support block and the mounting plate can only slide straight up and down. Once the support block is tilted by force, the sliding plate and the inner wall of the adjusting groove tilt and abut. Under the action of their contact friction, the distance between the support block and the mounting plate does not change significantly, thereby achieving the balancing effect of the support wheel of the support arm.

[0014] 2. By connecting the mounting plate and the fixing block, the mounting plate is fixed on the support arm. The mounting plate is then connected to the screw, and the screw is connected to the screw groove, which provides support for the mounting plate on the fixing block. This improves the stability of the mounting plate and facilitates its disassembly and replacement on the support arm. Attached Figure Description

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A device for controlling the balance of a forklift support wheel includes a support arm 1 and a mounting plate 2. A fixing block 3 is fixedly connected to the outer surface of the support arm 1. The mounting plate 2 is connected to the outer surface of the support arm 1 through the fixing block 3. A screw 4 is connected through the surface of the mounting plate 2. An adjusting block 5 is fixedly connected to the surface of the mounting plate 2. An adjusting groove 51 is formed on the surface of the adjusting block 51. A limit groove 52 is formed on the inner side of the adjusting groove 51. A sliding plate 8 is slidably connected to the inner side of the adjusting groove 51. A support block 6 is fixedly connected to the surface of the sliding plate 8. A rotating wheel 7 is movably connected to the side of the support block 6 away from the sliding plate 8. Through the connection of the support arm 1 and the fixing block 3, and the connection of the fixing block 3 and the mounting plate 2, the support effect of the support block 6 and the rotating wheel 7 at their respective positions is achieved.

[0024] Furthermore, the mounting plate 2 has a "U" shaped cross section, and the fixing block 3 has an "L" shaped cross section. The mounting plate 2 and the fixing block 3 are connected by a hook, which facilitates the installation of the mounting plate 2 on the support arm 1.

[0025] Furthermore, a through hole is provided on the surface of the mounting plate 2, through which the screw 4 passes. The through hole on the mounting plate 2 enables the screw 4 to pass through and connect to the mounting plate 2, facilitating the support operation of the screw 4 on the mounting plate 2 at the installation position on the fixing block 3.

[0026] Furthermore, the outer surface of the fixing block 3 is provided with a screw groove 41, and the screw 4 and the screw groove 41 are threadedly connected. The mounting plate 2 is connected to the fixing block 3 through the screw 4 and the screw groove 41. Through the connection between the fixing block 3 and the screw groove 41, the screw 4 and the screw groove 41 are threadedly connected to achieve the effect of fixing and supporting the mounting plate 2 on the fixing block 3.

[0027] Furthermore, a limiting block 81 is fixedly connected to the outer surface of the slide plate 8. The limiting block 81 and the limiting groove 52 are slidably connected. Through the connection between the slide plate 8 and the limiting block 81, the sliding angle of the slide plate 8 within the adjusting block 5 is limited by the sliding connection between the limiting block 81 and the limiting groove 52.

[0028] Furthermore, the slide plate 8 is slidably connected to the adjustment block 5 via the adjustment groove 51, and the support block 6 is positioned below the adjustment block 5 via the slide plate 8.

The outer surface of the slide plates 8 and the inner wall of the adjustment groove 51 are slidably connected. The support block 6 and the mounting plate 2 are distributed on both sides of the support arm 1. With the corresponding sliding connection between the slide plates 8 and the adjustment groove 51, the vertical sliding between the support block 6 and the mounting plate 2 can be maintained, and they will not slide under the tilted force state, thus achieving the effect of balancing the use of the support wheel on the support arm 1.

[0030] Working principle: When installing the mounting plate 2, the mounting plate 2 is hooked onto the fixing block 3, and then the screw 4 is installed in the through hole on the mounting plate 2, so that the screw 4 and the screw groove 41 are threadedly connected, which enhances the connection stability between the mounting plate 2 and the fixing block 3. With the connection of the adjusting block 5 and the adjusting groove 51, the connection of the sliding plate 8 and the adjusting groove 51, and the sliding connection of the limiting groove 52 and the limiting block 81, the distance between the support block 6 and the adjusting block 5 is adjustable. With the connection of the support block 6 and the rotating wheel 7, a balanced support effect is achieved for the support arm 1.
